Title: Improvements in magazine talking machines
IPC: G11B17/16
Filed: 1934-01-22
Abstract: 429,635. Magazine gramophones. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, and THOMPSETT, H. A., 26, Castlebar Park, Ealing, London. Jan. 22, 1934, No. 2248. Addition to 419,299. [Class 40 (ii)] In a magazine gramophone as claimed in the parent Specification, means are provided to enable the motor to be started and an automatic cycle of operations initiated by a single manual operation which does not involve handling the reproducer. The said automatic cycle comprises lifting the pick-up arm, swinging it outwards, feeding a record from the magazine to the turntable, swinging the pick-up arm to a position over the edge of the record and finally lowering it on to the record, and it is effected by a number of cams on a shaft 19 which performs a single revolution during the whole cycle. The shaft 19 is driven by gearing from a disc 2 which is adapted to be clutched in known manner, when required, to the turntable spindle 1. The clutch lever 3 is normally held out of action by means of a detent 9, which is controlled by a three-armed lever 12 coacting with a notched ring 20 on the camshaft 19. When the last record of a series has been played, the machine is stopped, as described in the parent Specification, by depression of a rod 26 by the pick-up arm, the rod operating a switch or brake. According to this invention, the machine is restarted after the magazine has been reloaded, by depressing a knob 38, whereby a lever 32 is rocked, and by lifting the post 26 with the pick-up arm on it allows a lever 28 carrying a mercury switch 27 to tilt and close the motor circuit. At the same time, the lever 32 raises an arm 42 projecting from a bar 41 which is pivoted between brackets 40. The bar 41 being thus rocked thrusts a rod 44 against a pin 47 on the detent 9, so that the detent is moved and allows the clutch lever 3 to engage its driving member 6. This sets the camshaft 19 in motion and initiates the cycle of operations effected by the cams.

Title: Improvements in insulated electric conductors and other insulated electric apparatus
IPC: C08B3/06
Filed: 1931-01-23
Abstract: In order to increase the insulation resistance of a cellulosic fibrous material such as yarn, woven fabric, papers, fibres, &c. for insulating conductors or other electrical apparatus, the material is treated with reagents which gradually convert the cellulose into esters or ethers, the time of treatment and optimum temperature being experimentally determined.  In an example, loose cotton cops are immersed in a bath of acetic anhydride, a dehydrating catalyst and glacial acetic acid, the cellulose being substantially converted into the mono-acetic condition.  The esterified product is freed from reagents by washing.  A bath comprising by weight 20 per cent acetic anhydride, 10 per cent anhydrous zinc chloride, and 70 per cent glacial acetic is p  preferably used and is stated to take twenty hours to convert the fibres, undiminished in mechanical strength, to monoacetate at 40 DEG  C.  Specification 280,493, [Class 2 (ii), Cellulose &c.], is referred to.

Filed: 1940-02-08
Abstract: 635,962. Injection-moulding rubber. QUILLERY, H. P. M. Feb. 8, 1940, No. 2405. Convention date, Feb. 8, 1939. [Class 87 (ii)] A vulcanizable rubber mixture is injected quickly into a closed mould maintained at a high vulcanizing temperature of the order of 200‹ C. for example. Before injection the rubber may be preheated to about 80‹ C. The rubber may be freed from air before it enters the mould. Rubber mix is fed, as by a milling machine, to a pot 16, Fig. 1, supported on a fixed plate 5, and is forced by a hydraulic plunger 25 through a perforated plate 23 and passage 18 into a mould 30. The mould is kept at a temperature of about 200‹ C. by means of heating plates 13, 14. The pot is kept at 80‹ C. The effect of the milling machine and the perforated plate 23 is to free the rubber from air bubbles. Escape ducts in the mould allow air to escape and limit the pressure inside the mould. Auxiliary jacks, not shown, lift the plate 27 that carries the plunger 25. Fig. 3 shows a modification in which the pot is filled by means of a screw 35 fixed to the piston 29 and rotated by gearing 38, 39. The Specification as open to inspection under Sect. 91 states that the-injection press may co-operate with two or more moulds carried by a rotary plate or a conveyer belt in such a manner that one can be filled while the others are being emptied. This subject-matter does not appear in the Specification as accepted.

Title: Detecting irregularities in the movement of elongate material
Inventor: MORGAN ROBERT FREDERICK JENKIN
IPC: C21D9/56
Filed: 1962-01-23
Abstract: In a process of and apparatus for detecting the slipping of elongate material relative to rotating guide means over which it passes through a treatment zone e.g. for annealing, galvanising or tinning, there are generated a first signal representing the peripheral speed of the guide means, and a second signal representing the speed of the material, and the two signals are compared.  The signals may be generated by transducers either of the digital or analogue type; a digital pulse generator is preferred but use of a tacho-generator is also referred to. The particular embodiment described comprises apparatus for the continuous heat treatment of strip in which strip 11 (Fig. 1, not shown) passes through preheating chamber 18 enclosing roller 31, through heating device 46, over roller 45 and through cooling zone 19 enclosing further roller 31, leaving by seal 48 to driving means 79 where it passes round bridle rolls 80 and 81 under such conditions that slip is obviated.  Rollers 31 each have stub shafts driving pulse generators 63 the signal from which are transmitted to counter 65.  Roller 45 similarly causes generator 75 to transmit a signal over line 76 to counter 65.  A further generator 83 attached to roller 80 transmits a signal representing movement of the strip to counter 85.  The outputs of counters 65 and of counter 85 are fed to comparator 86, which is so arranged that if any time count of any one input to counter 65 varies in relation to that of counter 85, the appropriate warning lamp 90 is illuminated and a signal is transmitted through line 92 to stop drive means 79.
